so it's not simply a barack obama phenomenon. but i don't. what we see both from my own work inside the senate and observation from what we see with books like mike grunwald's is that it was a very deliberate strategy hatched at least at inaugural if not before to try to raise the bar and to block things from happening, and to get unanimous minority support. and to do it not just on build 40 want to amendments, but on build where he had no interest, just make it all messy and make it difficult. i'm not going to defend barack obama's outreach to the minority party, but i could go back to knot the use of the filibuster but other methods of obstruction with bill clinton who reached out all the time. so i think that's the factor but a minor one. i think harry reid's use of filling the amendment tree, partly this is chicken and egg, but has been done too much and that didn't result in at least some protests and willingness of some senators on his side who might otherwise have joined in some of these filibusters to do so. it had much more to do wit
